FIELD OF THE INVENTION

[0001] The present invention relates generally to personal computers and, more particularly, to a computer provided with an access door for a modular data storage media drive. Even more particularly, the present invention relates to a computer in a tower configuration provided with an access door for a modular data storage media drive.

BACKGROUND OF THE INVENTION

[0002] Personal computers have become smaller and smaller. One common configuration which reduces the footprint of a computer is a computer having a tower configuration. A tower computer has a relatively small width and relatively larger height and length dimensions.

[0003] Because of the reduced size of the newer personal computers, it is necessary to pack the components into a smaller space. However, the more tightly packed the components are, the more difficult it is to assemble and disassemble a computer. For example, it is difficult for a computer owner or repair person to perform warranty repair work if the computer configuration does not provide easy access to various components which may require maintenance or replacement during the life of the computer. In densely packed housings, it is often necessary to go through the tedious process of removing one or more components using special tools and techniques in order to gain access to the component which must be tested or replaced. This can be extremely expensive for the computer manufacturer in the event that a modular data storage media drive needs to be tested or replaced. In the event that the drive needs to be tested or replaced it may be necessary to either ship the computer case to a repair facility or have a computer technical personally go to repair the disabled computer.

[0004] Thus, a need exists for an apparatus and method which allows a modular data storage media drive to be easily replaced or upgraded, maintained and repaired without requiring the computer to be shipped to a repair facility and without having to have a computer technician go to an on-site location to test and/or repair the disabled computer.

BEST MODE FOR CARRYING OUT THE INVENTION

[0024] Refer now to FIG. 1 where a computer case, generally indicated at 20, is illustrated. The computer case 20 is illustrated in a tower configuration and includes a sidewall 30 which includes an access door assembly, generally indicated at 50, according to the present invention. It should be understood that the present invention is equally applicable to any computer case configuration and is particularly applicable in configurations where the size of the computer case has been minimized or reduced. Also, although the access door assembly is depicted in a horizontal configuration, it is also usable in a vertical configuration. As depicted in FIG. 1, the access door assembly 50 is illustrated in a closed position.

[0025] Refer now to FIG. 2 wherein the access door assembly 50 is depicted in an open position in dashed lines. The access door assembly 50 has been pivoted in a counter clockwise direction away from the sidewall 30 as shown in FIG. 2.

[0026] Refer now to FIG. 3 where an enlarged view of an opening 60 formed in the side panel 30 is illustrated into which the access door assembly 50 is positioned. The opening 60 has a generally rectangular configuration with four edges 62, 64, 66, 68. Two elongated slots 70, 72 are formed in cut out portions 71, 73 respectively which extend inwardly from the wall 62 and parallel thereto and each has a rectangular shape. Extending inwardly from the wall 66 are two elongated slots 74, 76 which are formed in cut out portions 75, 77, respectively. Slots 74, 76 extend inwardly from wall 66 further than slots 70, 72 extend from wall 60, 62. Slots 70, 72 are directly opposite and of the same length as slots 74, 76 although the slots can be of any length. The slots 74, 76 are parallel to the wall 66.

[0027] Refer now to FIGS. 4A-4E. An access door generally indicated at 100 used in the access door assembly 50 is illustrated according to the present invention. The access door 100 includes an enclosure portion 102 which is generally flat and has an outer surface 104 and an inner surface 106. The outer surface 104 is generally flush with the outer surface of side panel 30 when the door assembly 50 is in the closed position as depicted in FIG. 1. Extending from surface 106 is a wall 110 and a second wall 112. A plurality of vents 116 are formed in the enclosure portion 102 to allow for ventilation and to space the media drive 200 from the inner surface 106. Enclosure portion 102 has peripheral edges 120, 122, 124, 126. Preferably, the access door 100 is a one-piece stamping.

[0028] A first set of L-shaped ramps 140, 142 are formed which extend from edge 128 inwardly towards wall 110. Ramps 140, 142 extend downwardly from surface 106 to engage with an inner surface of the side panel 30. Similarly, a second set of ramps 150, 152 extend from the edge 124 and from surface 106. Further, in walls 110 and 112, there are formed locking tabs 160, 162, 164, 166 which are formed by forming U-shaped cut outs in walls 110, 112, respectively. In this manner, tabs 160-166 can be bent inwardly to retain a modular media drive such as a floppy disk drive or a hard disk drive.

[0029] A downwardly extending lip 170 is formed on the edge 126. Downwardly extending lip 170 is separated by a flat outwardly extending portion 172. In this manner, the lip 172 can be located on an outer surface of the side panel 30 whereas downward lip 170 is located on an inner surface of the side panel 30 when the drive door 100 is located in the closed position. A fastener area 180 is located at approximate edge 122.

[0030] The drive door 100 is preferably formed as a single piece stamping with the walls 110 and 112 being bent transversely relative to the enclosure portion 102. The walls 110 are 112 are connected to the edges 128, 124, respectively by connecting portions 130, 132, respectively which are bent back onto the inner surface 106. The ramps 140, 142 are formed by forming cut outs 144, 146, respectively in the connecting portion 130 and then bending the ramps 140, 142 transverse relative to the enclosure potion 102. The ramps 150, 152 are formed by forming cut outs 154, 156 in the connecting portion 132 and then bending the ramps 150, 152 transverse relative to the enclosure portion 102.

[0031] As depicted in FIG. 5, a modular media drive 200 is depicted attached to drive door 100 via the locking tabs 160-166. For simplicity, cables connecting the media drive 200 to the PC board are omitted for clarity.

[0032] In operation, the media drive 200 would first be either attached or removed from the drive door 100. The cables would either be attached or detached depending on whether a media drive was being installed or removed. To install the drive door assembly 50 in the closed position depicted in FIG. 1, the access door assembly 50 would be positioned in recess 60 with tab 152 located in the slot 70, the tab 150 located in the slot 72, the tab 142 located in the slot 74, and the tab 140 located in the slot 76, respectively. Once the tabs 152, 150, 142, 140 are properly located in each of the slots, as depicted in FIG. 1, the access door assembly 50 would be moved to the right such that the ramps 150, 152, 140, 142 would engage an inner surface of the side panel 30. A fastener can then be used in fastener area 180 to secure the drive door assembly 100 to the side panel 30 in a known manner.

[0033] It should be appreciated with the media drive 20 positioned in the access door shown in FIG. 1 or 2 or entirely removed from the computer case as shown in FIG. 5 that the entire media drive is easily accessible. Thus, a user may quickly and easily upgrade and/or repair the media drive without using special tools and without technical skills or training. Similarly, a technician can easily access the interior of the computer case by opening the access door. In the illustrated embodiment, it is only necessary to remove a fastener from the side of the access door; open the door by pivoting it in the direction shown in FIG. 2 and, if necessary, remove cables from the media drive. The entire operation can typically be performed by a person with no technical experience who has recently performed the same operation at least once before, in less than three minutes. Thus, the entire removable media drive is readily accessible. The phrase “readily accessible” when used herein to refer to a computer component such as a media drive means that unobstructed access may be obtained so that computer component by an average person, with no technical experience who recently performed the same operation at least once before, in less than three minutes and without using special tools.

[0034] It will be appreciated that providing a computer case with a drive door assembly having a media drive, such as a floppy disc drive or a hard disc drive, such as described above, provides many benefits to both a user and to a computer service department. For example, if a user desires to have work performed on a defective hard drive, the user can easily remove it and ship it to a repair site without going through the considerable trouble of packing and shipping the entire computer. Furthermore, the individual may be able to continue to use their computer without the hard drive if the user has other drives. Another benefit is that a computer operator who requires service to another portion of its computer may remove and retain the hard drive before shipping the computer and thus retain control over the hard drive and possibly sensitive data contained thereon. Also, the user may use the removable hard drive in the same manner that a computer user uses removal in the media. For example, a computer which is shared by multiple users, each user might own and retain their own hard drive which the user manually installs at the beginning of an operating session. Removable hard drive is, of course, of great benefit to a repair facility which may easily replace a defective hard drive to the user, possibly while the user waits. The easily removable hard drive reduces labor time associated with hard drive repair or warranty service and thus is beneficial to the computer servicer as well as the computer user.

[0035] It should now be appreciated that a computer case and access door have been described which are very compact and allow the tower computer to occupy a relatively small foot print on a desk top. However, the manner in which the components are mounted in the computer allows easy access to the floppy drive and/or hard disk drive of the computer even in a relatively compact configuration. The floppy drive and hard drive can each be modular components each mounted on their own access door, thereby allowing easy removal and replacement/repair/inspection of these components. This access door also allows ready access to the interior of the computer case.

[0036] It will be readily seen by one of ordinary skill in the art that the present invention fulfills all of the objects set forth above. After reading the foregoing specification, one of ordinary skill will be able to affect various changes, substitutions of equivalents and various other aspects of the invention as broadly disclosed herein.
